Solid Work and Auto-cad Application - Assignment Example

CAD APPLICATION Name Name of class Tutor Name of school City and State Date Part 3 Technical drawing, are as famously known, drafting is the process of composing images that adequately communicates how something works or how it can be constructed, the communication is a visual representation of the concepts applied in the drawing. Technical drawing a universal way of communicating in engineering and related technical fields in general. To make the drawings communicate a similar message to all practitioners, people use symbols, notation systems, common units of measurements, perspectives, visual layouts and language that removes the ambiguity in the diagram developed. The drawing standards and conventions are have been summarized into a conventional system that communicate adequately to the users of such information and transcends the boundaries of language making technical drawings to acquire status that allows it to act as universal mean of communicating technical concepts by use of diagrams. The summations of rules regarding the universal language used in technical drawings are the drawing standards. Drawing standards entails all the detailing that are conventionally needed to communicate the information about a component. It controls the indication of information essential to fabricate a component, specify the standards of a component and how to assembly the parts detailed into the objective item. To do this, drawing standards therefore controls the units system used, angle of presentation, dimensioning system, symbols applied and material specifications. These standards plays critical roles in the functioning of the industry. It is only possible to achieve universal understanding when there is common way of communication. Drawing standards defines how certain information must be represented in a drawing, the guidelines are understandable to every industry participant hence they can interpret the information that the drafter presents. The standards also provides a way of evaluating the nature of product, it is possible to define potential failure, mismatch or error that would result in the final product from the drawings if standards are observed. Besides the ability to project results, standards in a drawing allow the expression of a component in different view and stages of assembly. The use of 3D and 2D drawings have dominated the industry, mostly from manufacturing firms and building construction. 2D drawing the presentation of a part in two of the three angles, this can be front and side view or the plan and other angle projection. In 3D drawing, the object is presented in all the three angles. This object can be the whole assembly or just a particular part of the desired object. Figure A and B below illustrates 3D and 2D drawings respectively Often, manufacturers use drawings as a way of gaining a sales leadership besides the technical role of fabrication. By posting CAD files of desired component by the manufacturer, potential buyers are able to download this parts and customize them into dimensions that fits their specific need. Such CAD files are therefore a way of communication between the manufacturer and the client. An object can be modelled in a CAD file and printed out just as modelled. Modern building require a detailed plan in form of drawing from which the actual structure will be built, the drawing used are a mixture of both 2D and 3D indicating different components. CAD file are also critical in the industry in helping the designer to arrive at a final decision regarding the product and have a post-output view of the intended product. While at the design stage, CAD files are effective in the identification and cutting down of BOMs errors that might end up the final product. The client also used minimal time in verbal description of their desired part of they are able to present them in CAD in files, all the details of the product can therefore be modeled without errors using the specifications provided, in addition, cases of miss communication are minimized with the use of CAD files. In business terms, 2D and 3D CAD files offer a great industry lead to manufacturers who use CAD to communicate with clients, other engineers, implementation of design and marketing. From my personal perspective, the use of CAD in modelling was a challenge at first by I come to appreciate its application as I learnt to use its features. Initially, understanding how to use CAD in modelling from written guides seemed to be a challenge to me, since there are different versions of CAD and a variety of preset settings would also be affecting ones working at a time, successfully performing a drawing from scratch was a challenge. In summary, it was difficult to understand how to use CAD software from theoretical perspective of its working. I eventually overcome such challenges with the help of practical lessons. Learning how to perform certain operation with hands on gave me a working understanding of the technology. The ease with which it is easy to make drawings in using CAD by far supersedes manual drawing by hand on paper. It is much easy to get the exact measurement of any drawing when using a computer than when drawing by hand, besides the ability to measure accurately, drawing of lines is much easier by application of commands that translates into ones accurate specifications. Modelling by CAD is less time consuming as compared to manual modelling. For instance, it takes several minutes to get the exact measurement of a line, accurately making a straight line from a drawing edge, in addition, the resultant line might to be at perfect angle and intersecting with other lines as desired. However, with the help of CAD, I would easily draw perfect lines just by using the line command in a fraction of a minute. In manual drawing, the drafter must manually draw the object at different angles in order to present all the possible views of the object as 3D or 2D. This was not the case when I used CAD in modelling, I would rotate the object into different projects and angles and print out each phase individually. Manually drawn models are relatively rigid as compared to CAD drawings. In manual drafting, is difficult to make changes to a given component and leave the other parts unaffected, in same cases, erasing and might leave the final work untidy. However, its easy to makes changes to drawings in CAD without compromising other parts. Features such as delete, erase, extend, cut and mirror makes drawings to be easily editable without having to interfere with other components. Some features such software like Solid Work allows one test if the component will match, this is impossible when drawing manually. My experience with CAD in modelling have been better than manual drawing.
